HERMANNKLOPPE, or CHARLQTTENBURG, GERMANY ILLUMINATED FOUNTAIN -npplieation'siea June 11, 1925, serial Nasa/11e, 'and incermany 11111612, 1924. 'i

My invention relates to improvements in illuminated fountains, and more particularly in fountains of the-type in which light of different colors is thrown into the jets .of water.

v; 5 The object of the improvements is to provide a fountain of this .type by means of which a great variation of the color edects'can be produced, and with this object in view myinvention consists in providing a plurality of multi-color filters one behind the otherin the direction of the lightfalling into the jets of water', and providing means for shifting the said color filters relatively to each other so as to set fields of varying colors one behind` the .15 other in the path of thelight rays. yPreferably one of the said filters is provided with fields having comparatively deep colors, while the other one, which is designed for varying the light passing through the first-nained nlter, has fields of comparat'vely lightk colors,

so that the brilliancy of the light passing through both filters is not reducedias much as when the field colors in both filters are comparatively deep.

, Z" Another objectof the improvements is to 'lprovide a fountain which is provided with va Y refractive rim constructedso as to collect the jets of water falling downwardly into .the basin, and further to refract the light emanating from the water of the fountain collected within the basin, which water is likewise colored by the light passing through the color filters. Preferably the said rim of transparent material consists of glass having depressions or projections cut or pressed thereon,

which projections or depressions refract or disperse the successive colored rays emanating from the water and have a beautiful illuminating effect. The rim of glass, which col- .43 lects the water falling from the fountain, prevents spoiling of the decorative. mounting of the fountain by the drops of Water. The said glass rim may be made integral with the basin of the fountain.

For thepurpose of explaining the invention an example embodying the saine has been shown in the accompanying drawing, in

which the same reference characters have been used 1n all the views to indicate corresponding y 9 parts.

In said drawing,

` saidcolors being for example green, blue, red,

F ig. 4 is a partial sectional elevation on an 55 enlarged scalershowing the said rim andthe basin, v f

Fig. 5 is a sectionalelevation showing the top part ofthe fountain, and K Figs. 6 and 7 are top plan vie-Ws showing the color filters.L f In the exampleV shown in the -figures the fountain comprises abasin 9 supported on legs f 10, an axial pipe 11 vfor thesupply of Watery under pressure and having a nozzle 12 at its 65 top, a source of light represented in Fig. 5 by two incandescent electric lamps 13, and color filters 14 and 15.l The bottom of the kbasin 9 is provided with two panes 16 oftransparent `mate-rial, whichpanes are located above the lamps 13 and the color`filtersvl4 and 15.. The

`color filters 14 and 15 are adapted to be rotated relatively to each other. As shown the Alower filt'erl is connected with a gear wheel nected'with a'gear wheel 19 engagedby. apinion 20, which is likewise connected with asuit- U abledriving mechanism. .The pinions 18 and 20` are operated so as to shift'the filters lf14eand 15 relatively to'each other and successively to place different fields of the filters into position below the transparent panes V16. 85

In Fig. 6 I have shown a plan view of the j upper filterV 15. As shownvthe said filter is divided into sectors of different colors, the

90 orange,white, green, blue,red,lorange ,and

white. In Fig. 7 I have shown a plan view of `the filter 14, which filter is divided into sectors having comparatively light colors. As

. ing Vli,'glitcolor -tints: On the top of the basin thereinarimQQ of transparent material such as iglasshaving depressions or projections 23 cut or pressed therein., Preferably the said ico The operation of the fountain is as follows Water under pressure. is supplied through the pipe 11 and the nozzle 12, the said water issuing from the nozzle 12 in the form of jets. The lamps 13, 13 are illuminated, and the light from the said lamps is directed upwardly through the color filters 14, 15, the transparent panes 16, the water confined within the basin 9 and into the jets of water produced by the nozzle 12. Thus the j ets and drops of water are illuminated, and further, the 'c'olored light rays passing through the water and impinging on the rim 22 are refracted, thus producing a beautiful color effect around the fountain. By rotating the filters 14 and 15 at different velocities or in opposite directions continuously new combinations of color fields of the filters are moved into the paths of the lamps 13, 13, so that a great variety of the light effects is produced.

While in describing the invention reference has been made to a particular example em` bodying the same I wish it to be understood that my invention is not limited to the construction 4shown in the drawing, and that various changes may be made in the general arrangement of the apparatus and the construction of its parts without departing from the invention.

I claim: 1. A basin for a fountain comprising a bottom having spaced parts permitting the passage of light arranged about a central point of the basin. said bottom having other parts through which the passage of light is prevented. said spaced parts permitting the passage of light however being adapted to prevent the passage of water therethrough.

2. A basin for a fountain comprising a bottorn having a plurality of light transmitting sectors separated by sectors through which the passage of light is prevented, said sectors being arranged about a central point of said basin and said light transmitting seetors being impassable by water.

3. A fountain comprising a basin having a plurality of light transmitting sectors separated by sectors through which the passage of light is impeded, said sectors being arranged about a central point of said basin and said light transmitting sectors being impassable by water, means for dispersing a liquid above said sectors, means illuminating said light transmitting sectors from below and means for varying the color of the illumination.

4. A fountain comprising in combination a basin having lateral portions of its bottom at intervals adapted to transmit light but to impede the passage of water, means for dis- 4 persing a liquid above said basin and said lateral portions, means for producing light to be passed from below said basin through said portions adapted to transmit light, and

means for varying the color of the light from said light producing means.

5. A fountain comprising in combination a basin having lateral portions of its bottom at intervals adapted to transmit light but to impede the passage of water, means for dispersing a liquid above the bottom of the basin and also above said lateral portions, means for producing light to be passed from below said basin through said portions adapted to transmit light, light filters having various color sections in the path of the light from said light producing means and means for causing relative motion of said filters.

6. In combination in a fountain, a basin, means for illuminating the interior of said basin, a light refr-actor arranged about the edges of said basin and extending above the same, the said light refractorbeing open at its top and bottom to permit the free elevation and return of water therethrough and having refracting portions inclined towards the center of said basin.

7. In combination in a fountain, a basin, means for illuminating the interior of said basin and the lspace above said basin, co'nical means for producing dispersion of-light, said conical means having an open bottom, the edges of its open bottom being positioned near the edges of the basin and its inclined walls leaning towards the center of the basin and extending above the edges of the basin.

8. A basin having means for illuminating the interior thereof in combination with means adapted to produce dispersion of light arranged about the basin and rising above the edge thereof.

9. In combination with a basin of a luminous fountain, means for producing dispersion of light arranged 'about the basin near the edge thereof and inclined towards the center of the basin.

In testimony whereof I hereunto aiix my signature. Y p
